Cyanide-free alkaline zinc nickel alloy additive(MX-ZN510)

Nickel contains 12-15%, great corrosion resistance, pass neutral salt spray test：over 240h for white rust, over 720h for red rust. Good heat resistance, HV350-450 in Vicker's hardness, 750-800℃ in melting point, applicable for automobile engine. Good soldering, ductility, flexibility, cohesion, low internal stress and produce no foams. Fine and smooth crystallization, free to adjust various brightness from super bright, bright to semi-bright. Get better corrosion after being processed with trivalent chromium blue passivation, color passivation, nature color passivation or blocking agent. Use insoluble nickel anode and zinc-dissolved tank. Easy to manage plating solution. Applicable for barrel and rack plating.

Trivalent Chromium Black Passivator for Zinc Plating(MX-Zn-D-31H)

Newly-designed environment-friendly zinc electroplating black passivation, no more use of metal salt, like silver, iron and nickel, as blackening compositions. No toxic metals, like silver, and hexavalent chromium in passivation solution. Easy to operate, stable solution, brightly black-colored. No use of iron salt to blackening the plating, good corrosion resistance, could reach more than 72 hours in NSS (neutral salt spray) test. Applicable to all kinds of zinc electroplating.

Potassium salt acid zinc plating brightening agent(MX-Zn-SG-01 )

MX-Zn-SG-01 can be adopted in a wide range of electrical density, good filling ability, fast plating rate, which ensures mirror effect and even, smooth plating.Soft plating, low brittleness, fine crystallization. The plating obtained are easy to be iridescently or blue-whitely passivated, then get fine passivated layers. High temperature resistance, it can be operated in a wide range of temperature

Non-cyanide alkaline zinc plating brightening agent (MX-Zn-JG-01 )

MX-Zn-JG-01 due to the iron anode, it’s no need to take the anode out during downtime. With good filling ability, the thickness variation can be controlled to the minimum limit. The distinctive physical properties allow it to be reprocessed, like, bending, rolling and clamping. Easy to manage in terms of plating solution’ composition, temperature and battery. Stable corrosion resistance can be acquired, if the passivation is carried out by passivation agent with no hexavalent chrome. Applicable to autopart.
